POLE2 - DNA polymerase epsilon 2, accessory subunit Gene

Also Known as DPE2

Species: Homo sapiens

Gene Type: protein coding
Gene ID: 5427

About POLE2

Cytogenetic location: 14q21.3 Genomic coordinates (GRCh38): 14:49,643,555-49,688,214 (from NCBI)

This gene has 13 transcripts (splice variants) and 201 orthologues. Broad expression in bone marrow (RPKM 3.7), appendix (RPKM 1.6) and 21 other tissues.

Summary

DNA Polymerase epsilon, which is involved in DNA repair and replication, is composed of a large catalytic subunit and a small accessory subunit. The protein encoded by this gene represents the small subunit (B). Defects in this gene have been linked to colorectal Cancer and to combined immunodeficiency. [provided by RefSeq, Jan 2017]
